The day someone can give a lengthy reasoning as to why this particular book is good then we can be all conversational about it.
It's a book about a quest for a Holy Grail, that ends by telling you where the Holy Grail is hidden. That's interesting to me and 25 million people.
It's themes are interesting. The theme of the sacred feminine is particularly interesting and relevant at a time when an evangelical Christian president of the United States is championing women's rights in the Muslim world.
Furthermore, the themes are accessible. (Last time I checked The Blind Assassin thread, no one knew what The Blind Assassin was supposed to represent.) Personally, I believe that clarity is a form of quality. Why write, if not to be understood?
Rule 17, Principles of Composition, The Elements of Style, "Omit needless words." Dan Brown does a better job of following this rule than Norman Mailer, who in the novel I just finished reading launches into a multi paragraph description of the main character's erection. (Now, if you'd rather read about an erection than a quest for the Holy Grail, that's fine. But I can't see how that makes you a better reader than me, or smarter, or more cultured or more sophisticated.) Unless you want to insist that Norman Mailer sucks too, but I'd be surprised to see anyone make that argument.
Pace matters. Brown keeps everything moving along. That's important, and if Stewart insists that it isn't, I will dig up his comment where he complains about nothing happening in something he was reading.
The Da Vinci Code is extremely detailed. The details are revealed in a very sophisticated manner. So sophisticated, in fact that millions of people believe them. That takes, if not artistry, at least craft.
Finally, the Catholic Church responded. If you can write something and the Catholic Church feels compelled to respond, you have accomplished something. A writer who accomplishes something is an accomplished writer.
I'll never criticize anyone for not liking something. Everyone is entitled to their opinions and it's OK not to like any book. But people who make comments like, "The Da Vinci Code has no theme," aren't highlighting their sophistication. They are showing the world that they can't recognize a theme.
